topic How does one add symbology in arcpy to a layer with symbology based on more than one field? in ArcMap Questions https://community.esri.com/t5/arcmap-questions/how-does-one-add-symbology-in-arcpy-to-a-layer/m-p/1247698#M4230 <P>Hello,&nbsp; I have a script that sets a definition query in an mxd and then adds all symbology (lyr.symbology.addAllValues()). However, I can only 'add all values' to layers with symbology based on just 'Unique Values', not 'Unique Values, many fields'. Is there a quick way to do this?</P> Thu, 12 Jan 2023 17:39:00 GMT rescobar 2023-01-12T17:39:00Z How does one add symbology in arcpy to a layer with symbology based on more than one field? https://community.esri.com/t5/arcmap-questions/how-does-one-add-symbology-in-arcpy-to-a-layer/m-p/1247698#M4230 <P>Hello,&nbsp; I have a script that sets a definition query in an mxd and then adds all symbology (lyr.symbology.addAllValues()).
